Options Trading News

A large bullish trader is playing for more time in Activision Blizzard.

optionMONSTER's Heat Seeker system shows that a trader sold 10,000 September 17 calls for $0.32 in volume below previous open interest of 69,602. At the same time, he or she bought 10,000 October 17 calls for $0.65 in volume far above open interest of just 383 contracts, indicating a new position at that strike.

The trader is apparently closing the September contracts, which expire at the end of next week, and rolling the long-call position forward. This adjustment, which cost at net $0.33, gives the investor another month for the trade to stock to rally. (See our Education section)

ATVI gained 0.41 percent to $17.04 yesterday. The game developer was at a high of $18.43 at the end of July after gapping up from the $15 level a week earlier.

Total option volume in ATVI was 20,966 contracts in the session, compared to a daily average of 3,518 for the last month.

The other Greeks (Gamma, Vega, and Theta) are calculated by using month and strike data, and not by individual option. These are called strike-based Greeks. Gamma, Theta, and Vega are all strike-based Greeks
